Thanks for a great package :) This is in response to ticket #71 - it adds the option for `requestDebounce` which debounces the `fetch` method. By default it's not enabled....

Cheers for building Salvattore, it's come in very useful :) We've used it on the website for the Waterford Institute of Technology. http://www.wit.ie/events

I tried adding tests for this, but wasn't sure how to handle variable values for the width and height so I added passes instead. Not sure what the best approach...
